Guaranteed Every Year 8 Marks Module 3: Vapor Power Cycles

Q1. A steam power plant operates on an ideal Rankine cycle between boiler pressure 3 MPa and condenser pressure 10 kPa. If steam leaves boiler as superheated steam at 350°C, calculate: (i) Turbine work output, (ii) Pump work input, (iii) Heat added in boiler, and (iv) Thermal efficiency of the cycle.

Key Points: Look up steam table: h1 at 3 MPa, 350°C; isentropic expansion s2=s1 to find x2 and h2; h3 = h_f at 10 kPa; pump work W_p = v3*(P1 - P2); h4 = h3 + W_p. Efficiency eta = (W_t - W_p) / (h1 - h4).
